Research project on multibody dynamics simulation for tractor tire-parameter estimation

Overview

This research project developed a multibody dynamics model for a 30 kW agricultural driving platform and used simulation to support tractor tire-parameter estimation. The work focused on building a full-vehicle tractor model, reproducing towing and turning responses, and linking vehicle-level simulation results with tire-model parameters.

The poster material presents a tractor and tire modeling workflow based on RecurDyn, Magic Formula tire modeling, towing-force simulation, steering-radius simulation, and comparison between experimental response data and simulation results.
